Here are 30 sample images taken with a "Beta" pre-production version of the new Pentax 645Z medium-format DSLR and the 55mm f/2.8 and 25mm f/4 lenses.

The Pentax 645Z is a medium format camera that handles very much like a regular DSLR. The 645Z features a 51.4MP CMOS sensor, ISO range from 100-204,800, tilting 3.2-inch 1037k-dot screen and even Full HD 1080 60i/30p/24p video.

At Ricoh Imaging's request, the sample images have been resized to 75% of their full 51 megapixel resolution.
